Michael Giberson

If you have a long political memory — say going back about two weeks, which now seems like ages ago — you might remember the furor over the “failure” of polls and prediction markets when Hillary Clinton won the New Hampshire Democratic primary.

Prediction market consultant Jed Christiansen provides the most thoughtful post-New Hampshire guide to reading the political prediction markets, with generous links to other sources.
